LETTER-SHEET ENVELOPE.

SPECIPTCATION forming part of Letters Patent No. 372,752, dated November 8, 1887.

Application filed June 2;; 1837.

ToaZZ whom it may concern Be it known that I, GEORGE P. HERNDo v, a citizen of the United States, residing at Birmingham, in the county of Jefferson and-State ofAlabama,have invented certain new and use-' ful Improvements in Letter-Sheet Envelopes;

tents during transportation substantially equal to that incident to the use of the, ordinary sep-.. arate euvelope,whiIe at the'same time the op-' erations offolding .and securing the lettersheet envelope may be effected ,with ease and celerity and the sheet opened without danger of tearing or mutilating the message.

In carrying out my invention I have devised the construction illustrated in the accompanying drawings, wherein A Figure 1 represents my improved lettersheet envelope before folding. Fig. 2 represents the same with the letter portion folded in place and one of the side flaps sealed thereto;

and Fig. 3 represents the same completely folded and readyfor mailing.

Similar letters of reference indicate similar parts throughout the several views.

A indicates that portion of the letter-sheet upon which 'the message isto be written. As illustrated in Fig. 2, this message portion of the sheet is designed to be folded inwardly in the usual manner, so as to be secured in position by the gummed. flaps, as hereinafter described. 5

B B indicate lines of perforations forming the boundary-lines of the upper portion .of the message-space, said lines of perforations being continued through the upper sealing-flap, G, which is gummed along its upper edges, as shown at b. In line'with the side edges of the 'sealingflap O are perforations c, spaced at some distance apart from eachother, which serve as guides in folding the side flaps, H H. These Serial No. 241,986. (No modell) of perforations, E E, parallel to the rows B B, the perforations c 0 being midway between the rows B and E. Beyond the rows E the side flaps, H, are g ummed, as shown.

Extending along the upper edge of the message portion of the envelope is a row of perforations, F, and beyond said row another parallel row of perforations} G, with intermediate perforations, f, midway between said rows and at a distance from each other.

the operation of the invention is as follows: The message being written upon the portion A, said portion is folded inwardly, as illustrated in Fig. 2. The side flaps, H, are then folded inwardly upon the line of perforations c, as indicated at the right hand of the figure; This folding brings the rows of perforations B and E opposite each other. Both side flaps having been folded in the manner described, the gum upon them is moistened and caused to adhere to the back of the letter-sheet. The top flap, G, is then folded upon the line of perforations f, thereby bringing the perfdrations F and G opposite each other. The gum along the edge of the flap 0 isthen moistened and to adhere to the back of the envelope, asshown in Fig. 3, in which condition the'letter-sheet envelope is ready for mailing, the address being written upon the opposite side. Before thesealing operation is completed suitableinclosures may be inserted within the folds of the letter-sheet, and will be retained within the formed envelope without danger of loss. In opening the sheet the outlying portions beyond Fig. 3 may be torn off, whereupon the message portion may be at once opened and read. A characteristic feature of my invention is that the folded edges of the flaps present, practically, a strong unbroken line of resistance, so that any inclosures in the folded envelope are lessliable to escape than in those constructions wherein one or more of the edges are provided with closely-spaced perforations.

Having thus described my invention, what I- claim, and desire to secure by Letters Patent, IS-

side flaps, H H, are providedeach with a row A letter-sheet envelope consisting of the the surrounding row of perforations shown in' The sheet being constructed as described,
